A new top tax rate of 39% will apply on personal income in excess of $180,000 for the 2021-2022 and later tax years. For most taxpayers this begins on 1 April 2021.

Your clients who are provisional tax payers may need to adjust their provisional tax payments throughout 2021 to account for the larger year-end tax bill.

There are corresponding changes to other tax types to align with the 39% rate. These can be found in the table below.
